Claims.

The object of my invention is to produce an inexpensive but eflicientequalizer mechanism for connecting two sliding table top sections insuch manner that sliding force applied to either of 5 said top sectionswill be automatically transmitted to the other section to produce propercoordinated movement thereof whereby the adjacent edges of said topsections may be contacted at the middle of the supporting frame oragainst the opposite edges of an interposed extension leaf.

The accompanying drawing, which is a plan with portions of the slidingtops broken away, illustrates my invention.

In the drawing 10, 10 indicate the side rails and 11, 11 the end railsof the usual leg-supported frame. Extending between the side rails,intermediate the end .rails are stretcher bars 12, 12 to which, andadjacent end rails 11, are secured the stationary slide bars 13, 13 withwhich vertically interlock slide bars 14 are secured to the under facesof the sliding tops 15.

Extending between the stretcher bars 12, to one side of the mediallength of the table, is a horizontal stretcher bar 16 to the innervertical edge of which may be secured the supporting brackets of afolding leaf 1'7.

Secured to the upper face of the stretcher bar 16 is a metal base strip18 to the opposite ends of which are pivoted levers l9 and 20. Pivotallyconnected to the outer end of each of levers 19 and 20 is a link 21 tothe outer end of each of which is pivotally connected a plate 22provided with appropriate perforations 23 at its ends to receivefastening screws passing upwardly into the adjacent sliding top section15.

Pivotally connected at 19 and 20, respectively, to the levers 19 and 20is a link 25 which is preferably, though not necessarily, provided witha longitudinally extending slot 26 into which is projected a pin 2'7carried by strip 18. the slot being so proportioned that pin 2'7 willengage one end thereof so as to limit the outwardly sliding movement ofthe table top sections, the inward movement of said sections being, ofcourse, limited by contact at their adjacent inner edges.

As shown in the drawing the parts are so proportioned that the totaltravel of the two sliding top sections will be equal when the adjacentinner edges of the sliding top sections are separated by an amount equalto the width of the extension leaf 17.

I claim as my invention:

1. In a sliding-top table, the combination with the leg-supported frameand two top sections slidably mounted thereon, of two levers pivotallyanchored on the main frame beneath the top sections with their fulcrumsspaced lengthwise of the line of slide of the sliding top sections, alink pivotally associated with each lever and the adjacent top section,and a connecting link extending between and connecting said levers insuch manner as to compel opposite movement of the link ends of saidlevers, and inter-engageable elements, one carried by the leg-supportedframe and the other by said connecting link to limit outward movement ofsaid levers.

2. In a sliding-top table, the combination with the leg-supported frameand two top sections slidably mounted thereon, of two levers pivotallyanchored on the main frame beneath the top sections with their fulcrumsspaced lengthwise of the line of slide of the sliding top section, alink pivotally associated with each lever and the 15 adjacent topsection, and a connecting link extending between and connecting saidlevers in such manner as to compel opposite movement of the link ends ofsaid levers.

3. An equalizer for sliding table tops comprising a base bar, two leverspivotally anchored at the opposite ends of said base bar, a connectorlink pivotally connected at its ends to said levers in such manner as tocompel opposite movement thereof, and two links each pivotally connectedto the outer end of one of said levers and provided at its outer endwith means by which it may be attached to a sliding section of a tabletop, and inter-engaging means carried respectively by the base bar andconnector link for limiting movement of the connector link relative tothe base bar in one direction 4. An equalizer for sliding table topscomprising a base bar, two levers pivotally anchored at the oppositeends of said base bar, a connector link pivotally connected at its endsto said levers in such manner as to compel opposite movement thereof,and two links each pivotally connected to the outer end of one of saidlevers and provided at its outer end with means by which it may beattached to a sliding section of a table top.

5. An equalizer for sliding table tops comprising a base bar, two leverspivotally anchored at the opposite ends of said base bar and eachprovided at its outer end with means for engagement with a sliding tabletop section, and a connector link pivotally connected at its ends tosaid levers in such manner as to compel opposite movement thereof.
